DigiSpark ATTINY85 USB PWM 5V microcontroller module for Arduino 8 MHz

DigiSpark ATTINY85 USB microcontroller module for Arduino

Miniature module based on the AtTiny85 microcontroller, fully compatible with Arduino IDE. Equipped with 6 I/O ports, 3 of which can operate as PWM outputs. Supply voltage is 5V from the USB port or 7-12V DC from the VIN port. The chip is clocked at a frequency of 8 MHz. The board has a built-in voltage regulator that allows powering from an external source. The module comes with a preloaded bootloader that handles the USB port without the need for additional converters.
